FloPinguin 17c1a6300f Trading in lakes 🚤 (#3653)
## Description:

- Widened port placement and warship spawn/patrol checks from
`isOcean`/`isOceanShore` to `isWater`/`isShore`, so ports can be built
on lake shores and ships can operate on lakes, we discussed it here:

src="https://github.com/user-attachments/assets/acf1e970-9631-4848-a0ed-6d0470616e1d"
/>

- Filtered `tradingPorts()` by water component so ports only attempt
trades with reachable ports - prevents silent path-not-found failures
across disconnected water bodies
- Applied the same water component filter when a captured trade ship
reroutes to its new owner's nearest port
- Removed the `WaterManager` fallback that force-marked isolated
water-nuked-tiles as ocean (no longer needed since lakes are now
navigable)
- Added a check to prevent nations from building ports on water bodies
that aren't accessible to other players

FloPinguin 7f7cbba12f Water-Nukes 💧 (#3604)
## Description:

Adds a new `waterNukes` game config option that causes nuclear
detonations to convert land tiles into water instead of just leaving
fallout. When enabled, nuked land tiles are batched and converted to
water each tick, with full terrain metadata updates including:

- Ocean bit propagation from adjacent ocean tiles (BFS flood fill)
- Magnitude recomputation via BFS from remaining coastlines
- Shoreline bit fix-up in a 2-ring neighborhood around converted tiles
- Minimap terrain sync (majority-rule downsampling)
- Throttled water navigation graph rebuild (every 20 ticks) for ship
pathfinding
- Ship executions detect graph rebuilds and refresh their pathfinders
- TransportShips auto-retreat if their destination becomes water
- Water nuke craters use a smoothed angular noise ring with a
bounding-box scan instead of the regular per-tile random coin flip with
BFS, producing clean blob-shaped craters without scattered land pixels
that players would have to boat to individually

The `TerrainLayer` now incrementally repaints tiles that changed terrain
type, and tile update packets encode the terrain byte alongside tile
state so clients can reflect water conversions in real time.

When `waterNukes` is disabled, behavior is unchanged (fallout only).

Includes a new test suite (WaterNukes.test.ts) covering the conversion
pipeline, ocean propagation, magnitude recalculation, shoreline updates,
and minimap sync.

Also adds a new public game modifier for the special rotation.

### The only problem
A bit of lag on impact. But otherwise it works great and is fun. Maybe
needs some followup improvements if it gets merged.
I think its very cool in baikal / four islands team games. Chip away the
territory of your opponents.
Its also fun to turn The Box / Alps into a water map (its actually
possible to boat-trade then)

VariableVince 21c286189e Perf/fix(NukeExecution/NukeTrajectoryPreviewLayer): unnecessary fetch and pass to listNukeBreakAlliance (#3546)
## Description:

Perf/fix: listNukeBreakAlliance doesn't ask for allySmallIds and doesn't
do anything with it. But both NukeExecution and
NukeTrajectoryPreviewLayer do fetch and pass allySmallIds to it.

Make allySmallIds optional, have wouldNukeBreakAlliance (which does use
allySmallIds) handle it potentially being undefined, and remove fetch
and pass of allySmallIds to listNukeBreakAlliance.

VariableVince eb51853b05 Perf/Fix: spawn and other functions that need closest by unit (#3243)
## Description:

Performance improvements.

- **PlayerImpl**: for _nukeSpawn_, cache config to const.
- **Other files**: for nukeSpawn and other functions doing the same,
introduce findClosestBy function.
- for **TradeShipExecution**, with the move from _distSortUnit_ to
_findClosestBy_, also add check if port isActive, !_isMarkedForDeletion_
and !_isUnderConstruction_. These checks should have been there already,
so now do it in one go to make use of the predicate isCandidate in
findClosestBy.
- for **TradeShipExectution.test.ts**, add mock functions for
_isMarkedForDeletion_ and _isUnderConstruction_ because of the above.
Also, set Unit tiles and Pathfinding node to actual valid TileRefs for
the testing map. This prevents NaN as return value from manhattanDist.
This problem was already present with the use of distSortUnit, but that
function just did NaN - NaN, returned the first and only port unit in
the array and called it a day. For findClosestBy we have to make sure
the predicate manhattanDist actually returns a number instead of NaN so
we need actually valid tiles. We now have a working test instead of a
test that actually silently failed like before.
- **PlayerImpl**: _warshipSpawn_ and _nukeSpawn_: Make use of the
isCandidate predicate of findClosestBy to have warshipSpawn not return
ports under construction or (smaller change) inactive. This fixes a bug
i have seen right away (where Warship spawns from under construction
Port).
Same for _nukeSpawn_ silos, don't return inactive silo just to be sure
now that we can easily add it to isCandidate predicate anyway. This
costs no performance in the _nukeSpawn_ benchmarks actually. This should
as a by-effecft fix an edge case bug i have seen, where a nuke is sent
from a phantom silo.

Some of this goes along with PR #3220 since playerImpl buildableUnits
makes use of the underlying spawn functions via canBuild. Just like
ConstructionExecution does. But i didn't want to add more to PR 3220
since there's already a lot in there.

The new function _findClosestBy_ could also be applied to some other
parts of code to benefit of it being faster, so i did that.

_findClosestBy_ uses _findMinimumBy_, which is a little more generic in
name. I think _findMinimumBy_ could be used by other parts of code,
while _findClosestBy_ is more clear naming for what it does now. But we
could ditch _findMinimumBy_ and just leave findClosestBy?

_And here a comparison in the flame charts:_

- based on the same replay and tried to get the performance recording
going at the same speed and length but always end up with small
differences
- because of a bug in replays currently, it puts you in with the same
clientID/persistantID currently. This means we can also record part of
what is normally only recordable with live human input (the

Mattia Migliorini 2ec12f0a3a Auto-reject alliance request when transport ship is sent to target player (#3477)
## Description:

When a player sends a transport ship toward another player's territory,
any pending alliance request from the target is now automatically
rejected.
This mirrors the behavior already in place for direct attacks,
preventing a player from exploiting a pending alliance request while
launching a naval invasion.

VariableVince 6952550014 Fix: player name and location on wrong spot on the map (#3455)
## Description:

Fixes https://github.com/openfrontio/OpenFrontIO/issues/1021

Fixes issue that has been there since the beginning. Player name and
location and conquest FX (swords) not being in the right place. It can
happen at any time during a game and can be game-breaking in that
regard.

This makes it hard to find players, especially when trying to eliminate
their last few tiles on some island. So when clicking name in
leaderboard > wrong tiles. And when seeing name > above wrong tiles. Bug
report:
https://discord.com/channels/1284581928254701718/1444669324571967680

Also, when removing those last tiles, the wait time between updates of
player location can make it frustrating to find and eliminate them fast.
You need 2-3 clicks on their name in leaderboard, before finally being
moved to their current location.


**Cause:**
largestClusterBoundingBox not being changed when last attack happened in
same tick removeClusters last ran.

**Fix:** 
Also call removeClusters, and therefore update largestClusterBoundingBox
, when LastTileChange was AT lastCalc tick.

**Also:** 
Run removeClusters if player owns less than 100 tiles, don't wait for
ticksPerClusterCalc in that case. This way, sniping off the last couple
of island tiles of the player is easier. So it doesn't take 2-3 clicks
bbut just 1 click on the player name in the Leaderboard before the
camera moves to the next little island they are on. Also their last
clusters are annexed faster, only helping with the faster cleanup.
I think this is an optional to the fix in this PR, but still an
important QoL fix for sniping those last tiles quickly.

**BEFORE:**

https://github.com/user-attachments/assets/0960a4d3-7f8b-4368-9531-8244356bff17

**AFTER:** (also notice how it now just takes 1 click in the leaderboard
to immediately go to their next location, not 2-3 clicks)

VariableVince 0dc8fbf129 Fix inverse annexation (#3448)
## Description:

An inverse annexation could happen where the small player (even with
0,01% tiles owned) could fully annex the large player.

**TL;DR:** basically wrong use of calculateBoundingBox in
surroundedBySamePlayer, feeding it all bordertiles, making enemyBox far
bigger than it actually was in some cases. Which resulted in enemyBox of
small player with two small clusters at some distance from each other,
being seen as inscribing the largest cluster of the bigger player. While
that largest cluster is actually the border tiles of the bigger player
surrounding the main cluster of the small player. Instead of an
annexation of small by bigger, small would incorrectly annex bigger
completely.

**Situation:** bigger player fully surrounds main cluster of smaller
player. Those border tiles are also the largest cluster of the bigger
player, for which surroundedBySamePlayer is called.
SurroundedBySamePlayer finds the small player as the only bordering
enemy of this cluster. Then it needs to check which of the two players
is surrounded by the other one. EnemyBox uses calculateBoundingBox with
all border tiles of the small player as argument. The small player also
has at least one seperate cluster elsewhere, could be on another island,
which count as border tiles too. The enemyBox from the main cluster of
the small player to the seperate cluster elsewhere, can be huge. Now
inscribed() is called and it determines that largest cluster box of the
bigger player (which was in fact calculated correctly, also making use
of calculateBoundingBox) is surrounded by the bigger enemyBox. And so
the small surrounded player fully annexes the bigger player.

**Fix:** instead of a global enemyBox, we only need the localEnemyBox
that touches the largest cluster of the bigger player. With that,
inscribed() can correctly conclude that largest cluster box surrounds
the localEnemyBox. As a matter of fact isSurrounded() already used the
same method to calculate its enemyBox as introduced by @scamiv for v30:
https://github.com/openfrontio/OpenFrontIO/pull/3127/changes#diff-fb1101a2b50dd7c353d082ff7a3351cff5469b8249b3ebca91c10573a3dfaaf1

- Change in PlayerExecution
- Added test NoInverseAnnexation.test.ts, which fails before and passes
after the fix

The bug was introduced in this commit 10 months ago:
https://github.com/openfrontio/OpenFrontIO/commit/c4381a9ad3828b06764ab1a21fc1514e37aacfd7

It has probably led to some weird annexations happening since then. The
bug could seemingly happen on any map. But was noted recently a few
times on square islands (Sierpinski) or maps (The Box/The Alps), where
the circumstances probably highten the chances of the bug occuring.

## Description:

For the next v30 fix version

<img width="868" height="364" alt="imaege"
src="https://github.com/user-attachments/assets/520a999c-67e7-4c57-8651-895ad9eeb73a"
/>

HvN balancing for the revamped difficulty steps of v30 sadly doesn't
really work out...
In medium difficulty games humans nearly always win (boring)
In hard difficulty games humans usually lose
It was intended differently...

So lets get rid of medium difficulty HvN, always use hard difficulty and
disable the donation-capability for public game nations.
That will tune the human winrate towards a middle ground at about 65% I
think. Which should be nice.
Easier than in v29 (was frustrating sometimes) but not as easy as it's
now.

We can only test this in prod lol

FloPinguin 3013133d08 Embrace the aftergame! 😄 (#3410)
## Description:

In v30 we have the following change to prevent teammates from destroying
your structures:

**Block nuking teammate structures** - Nukes blocked if they'd hit a
teammate's structure (that was possible by nuking oceans / rivers) (by
@FloPinguin)

Original idea was from Wonder.
I think it makes sense, but it has a side effect: The aftergame, which
many players love, will be dead because of this change.

<img width="835" height="103" alt="image"

/>

I think a lot of complaints will follow after v30 is live. 

So why not add a little bit of logic for the aftergame?
After a team wins/loses, players can nuke their teammates. No longer
need to aim for water. SAMs also intercept teammate nukes in this phase.

PGray be9ea14fe9 refactor: rename Bot to Tribe in internal execution code (#3372)
## Description

Follows up on #3290 which renamed the user-facing "Bots" to "Tribes".
This renames the internal implementation to match:

- `BotExecution` → `TribeExecution`
- `BotSpawner` → `TribeSpawner`
- `BotNames` → `TribeNames` (`BOT_NAME_*` → `TRIBE_NAME_*`)

All callers updated accordingly. `PlayerType.Bot` and `ColoredTeams.Bot`
are intentionally left unchanged as they are serialised wire-format
values.

Closes #3335

FloPinguin cf3e3a7a74 Fix bot/nation player ID collisions causing missing players 🔧 (#3354)
## Description:

BotSpawner used the same PRNG seed (simpleHash(gameID)) as
createGameRunner, causing bot IDs to collide with nation IDs. When a
bot's SpawnExecution found a nation with the same ID via hasPlayer(), it
silently reused that nation instead of creating a new player - resulting
in far fewer players than configured (e.g. ~670 instead of 800 with 400
bots + 400 nations) with no console warnings.

Offsets the BotSpawner seed by +2 to avoid the shared PRNG sequence
(matching the +1 pattern already used by Executor).

VariableVince e137fcaa6c Fix/Perf/Refactor: playerActions and buildableUnits, their callers and related types (#3220)
## Description:

TL;DR: it's faster.

buildableUnits is called via PlayerView.actions from UnitDisplay (each
tick without TileRef), BuildMenu (each tick when open), MainRadialMenu
(each tick when open), PlayerPanel (each tick when open),
StructureIconsLayer (when placing a building from build bar),
NukeTrajectoryPreviewLayer (when placing nuke, on tick when tile
changes), ClientGameRunner (on click to attack/auto-boat or hotkey B or
G).

After https://github.com/openfrontio/OpenFrontIO/pull/3213 got merged,
the change with largest impact in
https://github.com/openfrontio/OpenFrontIO/pull/3193 was done in such a
different way that a new PR was needed

The idea in 3193 was to not always ask for Transport Ship from
buildableUnits. In such a way that very little extra data was send to
the worker. This had the biggest impact on performance (the idea was
months older btw, see
https://github.com/openfrontio/OpenFrontIO/pull/2295). Now, we do it the
other way around, by telling buildableUnits all unit types we want. Or
we want them all (undefined). The downside is more data is send in the
worker message. The upside is we have more options and can add more in
this PR.

This PR implements some of the leftovers in 3193 on top of 3213 and adds
further improvements.

(Some unrelated refactor/perf changes where moved out of this PR and
into already merged
https://github.com/openfrontio/OpenFrontIO/pull/3233,

https://github.com/openfrontio/OpenFrontIO/pull/3238,
https://github.com/openfrontio/OpenFrontIO/pull/3239)

- **GameRunner**, **WorkerMessages**: _playerActions_ and
_PlayerActionsMessage ._ Option to ask for no buildable units (null). It
now has 3 modes: get all actions and all buildings (units undefined),
get all actions and no buildings (units null), or get all actions and
specific building (units contains Unit Types).

- **GameRunner**: _playerActions_. fixes wrong assumption in PR 3213:
that only if units was undefined, we have to know canAttack.
ClientGameRunner wants to know both, in case of a click on non-bordering
land, to decide if it should auto-boat using a Transport Ship. So units
is not undefined (we only ask for Transport Ship now which has a
positive effect on performance for each click/tap) but we need canAttack
still.
Solved by removing the unit === undefined check before _canAttack_ in
_playerActions_.

- **GameRunner**, **GameView**, **WorkerClient**, **WorkerMessages**,
**Worker.worker**: added _playerBuildables_ / _buildables_ next to
existing _playerActions_ / _actions_. With above solved, there was still
no option to only get buildable units when the actions are not needed.
While **StructureIconsLayer**, **NukeTrajectoryPreviewLayer**,
**BuildMenu** and **UnitDisplay** need only that. To not make
playerActions more convoluted with more params or so, i've added a new
function _playerBuildables_ in **GameView** to only get buildable units
(**GameRunner** _playerBuildables_). _playerBuildables_ has 2 modes: get
all buildings (units undefined) or get specific buildings (units
contains Unit Types). Also update some comments that mentioned .actions
in **NukeTrajectoryPreviewLayer**.

- **ClientGameRunner**, **PlayerPanel**, **BuildMenu**, **UnitDisplay**,
**StructureIconsLayer** and **NukeTrajectoryPreviewLayer**: Since PR
3213, **StructureIconsLayer** and **NukeTrajectoryPreviewLayer** ask for
specific types of units from **GameView** _actions_ (**GameRunner**
playerActions). Now have the other files do the same. For example
**BuildMenu** asks for the new _BuildMenuTypes_ when it calls
._buildables_ and **ClientGameRunner** asks for UnitType.TransportShip
when sending a boat

- **ClientGameRunner**: canBoatAttack now accepts BuildableUnit[]
instead of PlayerActions so we can send it either actions.buildableUnits
or just buildables. Have functions call myPlayer.buildables(tileRef,
[UnitType.TransportShip]) when we only need a buildable unit and no
actions. Or myPlayer.actions(tileRef, null) when we need actions but no
buildable units. Or myPlayer.actions(tileRef, [UnitType.TransportShip])
when we need both actions, like canAttack, and a buildable unit. Then if
needed send either actions.buildableUnits or buildables to to
_canAutoBoat_ / _canBoatAttack_.

- **MainRadialMenu**: needs all player buildable unit types including
Transport Ship, so the _actions_ call argument for unit types can stay
undefined (unchanged) there.

- **MainRadialMenu**: now that **BuildMenu** uses _playerBuildables_
instead of _playerActions_, we must put data in
_this.buildMenu.playerBuildables_. And since we're not putting the
(unneeded) full _actions_ in there anymore, we can now put only the
needed and expected _actions._buildableUnits_ in it.

- **Game**, **PlayerImpl**, **StructureIconsLayer**: Typesafety and some
added perf: new type _PlayerBuildableUnitType_ (see also the below point
for how it is formed). So callers of _buildableUnits_ can never ask for
the wrong type like e.g. UnitType.Train because it doesn't return data
for that type. This type is now used in **PlayerImpl**, **BuildMenu**,
**RadialMenuElements**, **StructureDrawingUtils** and **UnitDisplay**
for that reason. And **InputHandler**, **StructureIconsLayer** and
**UIState** (little more on that in point below).

- **InputHandler**, **StructureIconsLayer**, **UIState**: In order to
make type safety work for GhostUnit.buildableUnit.type too (line ~217 of
StructureIconsLayer), changed type of interface _BuildableUnit_ to
_PlayerBuildableType_. Which is only more accurate. Same for and
this.structures and uiState.ghostStructure and with the latter,
_renderUnitItem_ in **UnitDisplay** and _setGhostStructure_ in
**InputHandler**. All Structures are of PlayerBuildableType (there are
even some in PlayerBuildables that aren't Structures, but it is much
more confined than UnitType).

- **Game**: Typesafety and some added perf: added _BuildMenus_ and
_BuildableAttacks_ in the same fashion that the existing StructureTypes
was already used (simplified it a bit too, with it renamed
_StructureTypes_ to _Structures_ and removed _isStructureType_). They
can be used with .types or .has(). _BuildableAttacks_.has() is used in
**RadialMenuElements**. _BuildableAttacks_ and existing _Structures_ now
make up _BuildMenus_. Which is used in **BuildMenu**,
**StructureIconsLayer** and **UnitDisplay**. Then _BuildMenus_ together
with UnitType.TransportShip make up the _PlayerBuildables_. Which is
used in **PlayerImpl** _buildableUnits_ (see point below). And with
_PlayerBuildableUnits_ we get the new _PlayerBuildableUnitType_ (see
above point on Game / PlayerImpl).

- **RadialMenuElements**: replace non-central ATTACK_UNIT_TYPES in
**RadialMenuElements** with centralized _BuildableAttackTypes_ too. Use
_PlayerBuildableUnitType_ for more type safety (can't by mistake add
UnitType.Train to its build menu). Make use of _BuildableAttackTypes_
instead of adding items hardcoded line by line in _getAllEnabledUnits_,
just like we already did since PR 3239 with _StructureTypes_. And use
_BuildableAttacks.types_ in the same fashion that existing
_isStructureTypes_ (now Structures.types) was already used elsewhere.

- **PlayerImpl**: _buildableUnits_ 
-- would do Object.values(UnitTypes) on every call. Now for better perf
directly loop over player buildable units by using _PlayerBuildables_
(see above point). In this way we also exclude MIRVWarhead, TradeShip,
Train, SamMissile and Shell so there are less unit types to loop through
by default. Since a player doesn't build those by themselves, they are
only build by Executions which use _canBuild_ directly and not
_buildableUnits_.
-- for more performance, do for loop instead of using .map and .filter,
no intermediate array needed nor callback overhead. We just loop over
the given units (which if undefined will contain _PlayerBuildables_).
Also pre-allocate the results array to get the most out of it, even if
V8 might already be very good at this.
-- cache config, railNetwork and inSpawnPhase so they can be re-used
inside the for loop.
-- cache cost inside the loop
-- it would check twice for tile!==null to decide to call
findUnitToUpgrade and canBuild. Now once.
-- eliminated double/triple checks for the same thing. It called
_findUnitToUpgrade_ (and with that _canUpgradeUnit_) and then _canBuild_
which both check if player has enough gold for the cost of the unit
type. And they both check if the unit type is disabled. Now we call
private functions _canBuildUnitType_, _canUpgradeUnitType_ to first do
checks on unit type level for early returns, and
_findExistingUnitToUpgrade_ to find existing unit without doing anything
extra. in a specific order to check everything only once. The public
functions _findUnitToUpgrade_ and _canBuild_ have an unchanged
functionality and we don't call them from _buildableUnits_ anymore.
-- would get _overlappingRailRoads_ and _computeGhostRailPaths_ when
canBuild was true. But this data is only meant for
**StructureIconsLayer** and it logically only uses it when placing a new
unit, not when upgrading one. Which is also commented on line 351 of
**StructureIconsLayer**. So, we now only get overlapping railroads and
ghost rails if we're not hovering to upgrade an existing unit.

- **PlayerImpl**: _findUnitToUpgrade_: unchanged functionality, but have
it call new private function _findExistingUnitToUpgrade_ to find
existing unit.

- **PlayerImpl**: _canBuild_: unchanged functionality, but have it call
new private function _canBuildUnitType_ to do the checks it first did
itself. And then new private function _canSpawnUnitType_ for the rest of
the checks. This way we can call _canBuildUnitType_ and
_canSpawnUnitType_ from _buildableUnits_ in a specific order to prevent
double/triple checks.

- **PlayerImpl**: _canBuildUnitType_: new private function to be shared
by _buildableUnits_, _canBuild_ and _canUpgradeUnit_ to be able do unit
type level checks in a specific order to prevent double/triple checks.
Via parameter knownCost, _buildableUnits_ can send it the cost it
already fetched so that it doesn't have to be fetched again. For caller
_canUpgradeUnit_, the isAlive() check (which was previously only done in
canBuild) is new but harmless, maybe even better to have also check
isAlive() on upgrade now that Nations are also upgrading which might
prevent some edge case bugs.

- **PlayerImpl**: _canUpgradeUnitType_: new private function to be
shared by _buildableUnits_ and _canUpgradeUnit_ to be able do unit type
level checks in a specific order to prevent double/triple checks.

- **PlayerImpl**: _canSpawnUnitType_: new private function to be shared
by _buildableUnits_ and _canBuildUnit_ to be able do unit type level
checks in a specific order to prevent double/triple checks.

- **PlayerImpl**: _findExistingUnitToUpgrade_: new private function to
be shared by _buildableUnits_ and _findUnitToUpgrade_ to be able do unit
level checks in a specific order to prevent double/triple checks.

- **PlayerImpl**: _isUnitValidToUpgrade_: new private function to be
shared by _buildableUnits_ and _canUpgradeUnit_ to be able do unit level
checks in a specific order to prevent double/triple checks.

- **PlayerImpl.test.ts**: because of the isAlive() check in which is new
for _canUpgradeUnit_ (see above at _canBuildUnitType_), the tests needed
to have the players be alive at the start, in order to pass.

- **BuildMenu**: use .find instead of .filter in canBuildOrUpgrade, a
function we already needed to change. This is faster and prevents an
allocation.


**PERFORMANCE**
As for calling ._buildables_ instead of unnecessarily getting
._actions_, there is an obvious win because there's less to send
calculate and recieve.

Also asking for only the needed buildings helps a lot (especially if
TradeShip isn't needed, see the difference in benchmark in original
#3193).

But the real-world impact is hard to measure. gave it a try in #3193 and
those results should be even better now.

Now testing only _buildableUnits_ performance in a synthetic benchmark,
we get these results. This is after other performance improvments so the
base is already better than it was in original #3193:

**BEFORE** (only buildableUnits itself)

Mattia Migliorini e1125e0c37 Fix: Nations reject alliance requests created pre-spawn (#3314)
## Description:

This PR fixes an exploit that allows the player to request alliances to
Nations, mostly in impossible mode, during spawn phase, with high
chances for it to be accepted due to troop count parity.

Nations now reject alliance requests during the spawn phase.

`GameImpl.executeNextTick()` initializes ALL pending `unInitExecs` in
one batch on the first post-spawn tick ( `numSpawnPhaseTurns() + 1` ).
So every alliance request submitted during spawn phase is guaranteed to
be created with `createdAt = numSpawnPhaseTurns() + 1` on the very first
post-spawn tick.
Therefore, we check for alliance requests created on the very first
post-spawn tick and reject those.

scamiv c911bfb2d8 Packed unit updates / MotionPlans (#3292)
## Description:

Reduce per-step `Unit` update traffic by shipping packed motion plans
and letting the client advance plan-driven units locally.

Changes:
- Add packed motion plan records (`packedMotionPlans?: Uint32Array`) to
game updates and transfer the buffer worker -> main.
- Introduce `src/core/game/MotionPlans.ts` (schema + pack/unpack) for
grid + train motion plans.
- Extend `Game` with `recordMotionPlan(...)` and
`drainPackedMotionPlans()`, and implement buffering/packing in
`GameImpl`.
- Treat units with motion plans as “plan-driven”: suppress per-tile
`Unit` updates on `move()` and advance positions client-side.
- Emit motion plans from executions:
- `TradeShipExecution`: record/update grid motion plans and `touch()`
when changing target after capture.
- `TransportShipExecution`: record initial plan and update it when
destination changes.
  - `TrainExecution`: record a train plan on init (engine + cars).
- Client: apply motion plans in `GameView` and ensure `UnitLayer`
updates sprites for motion-planned units even when no `Unit` updates
arrived.

bijx 7855e1b0e9 Feat: Troop transport retreats to closest owned tile v2 (#3286)
If this PR fixes an issue, link it below. If not, delete these two
lines.
Resolves #1139

## Description:

New version of the #2789 PR that is cleaner after changes made to old
pathfinding logic.

Adds logic to troop transport retreat behaviour which retreats a
transport to the closest owned tile instead of the source. Now if no
shores are detected (you lost all your shoreline while the transport was
out) we handle the return case same as if the original source was no
longer your territory.

Preparation for nuke wars, for v30.
Next PR will be adding the nuke wars modifier for public games, but
Wonders https://github.com/openfrontio/OpenFrontIO/pull/3224 needs to be
merged first to avoid merge conflicts.

### 1. Disable boats setting

It's possible to disable `UnitType.TransportShip` now. Because they are
not needed in nuke wars and can even be annoying.

/>

### 2. Team spawn zones for random spawn

Maps can have `teamGameSpawnAreas` in their json file now.
Spawn areas are currently active if 
- a supported map is chosen (Baikal Nuke Wars or Four Islands)
- a supported team size is chosen (2 teams on Baikal Nuke Wars or 2/4
teams on Four Islands)
- random spawn is enabled

Mattia Migliorini 6a30d2b38b Smarter factory placement for Nation AI 🤖 (#3244)
## Description:

Introduces a dedicated `factoryValue()` scoring function for AI factory
placement, replacing the generic `interiorStructureValue()` previously
shared with cities and missile silos.

Scoring criteria:
- High elevation and spacing from other factories (unchanged from
city/silo logic)
- Rail connectivity: bonus per distinct rail cluster reachable within
`trainStationMaxRange`, weighted by trade gold potential — allied
clusters score highest (1.0), team/neutral clusters score ~0.71, own
clusters ~0.29 (based on `config.tradeGold()` values). Based on
difficulty
- Cluster deduplication: connecting to the same cluster multiple times
does not inflate the score
- Embargoed and bot neighbors are excluded; all other non-embargoed
neighbors are included

The result is that the AI tends to place factories where they can bridge
separate rail networks or connect to high-value trade partners, rather
than deep in its own interior.

### EDIT

Added a dedicated `cityValue()` scoring function that takes into account
the connectivity score. This allows placement of cities in a
"factory-aware" way, while also enforcing spreading structures (we want
the network to grow, not a cluster of cities and factories all
together).

- Calculate the total interception capacity of all covering SAMs and
send enough bombs to overwhelm them (+1 extra per 5 needed to account
for enemy building more SAMs during flight)
- Plan launches in NukeExecution's Manhattan-distance silo order,
tracking which silos have interceptable trajectories (wasted bombs)
- Use a sliding window over parabolic flight times to find the best
cluster of bombs that can arrive within half the SAM cooldown window
- Compute per-bomb wait ticks to synchronize arrivals from silos at
different distances
- Skip launching if a salvo is already in flight
- Upgrade the best SAM-protected silo when silo capacity is
insufficient; wait and save gold when only gold is lacking

### 2-Player Endgame Handling (`NationNukeBehavior.ts`)

- On Hard/Impossible with only 2 players remaining,
`findBestNukeTarget()` directly targets the other player (bypasses all
priority logic)
- `getPerceivedNukeCost()` returns actual cost (no MIRV saving
inflation) when only 2 players are left

### SAM Build Rate (`NationStructureBehavior.ts`)

- Reduced SAM perceived cost increase per owned from 1.0 to 0.5, so
nations build more SAMs

### Island Attack Variety (`AiAttackBehavior.ts`)

- `findNearestIslandEnemy()` now collects up to 2 reachable candidates
and has a 33% chance to pick the second-nearest, adding variety to boat
attack targeting

FloPinguin 07b5d6e41f Prevent self-retaliation crash when own nuke destroys own ship 🔧 (#3260)
## Description:

Noticed this in two singleplayer games:

When a nation's nuke destroys its own transport/trade ship in the blast
radius, `NationWarshipBehavior` incorrectly tries to retaliate against
itself, calling `updateRelation(self)` which throws (GameRunner tick
error).

Added a self-check in `maybeRetaliateWithWarship` to skip retaliation
when the destroyer is the player itself.

scamiv f6a08e16db Perf alloc (#3241)
If this PR fixes an issue, link it below. If not, delete these two
lines.
Resolves #(issue number)

## Description:

## PR Title
perf(core): reduce hot-path allocations & safe optimizations

This PR brings in a set of allocation-focused optimizations in core hot
paths

### Scope
- `src/core/execution/NukeExecution.ts`
- `src/core/execution/WarshipExecution.ts`
- `src/core/game/UnitGrid.ts`
- `src/core/game/PlayerImpl.ts`
- `src/core/configuration/DefaultConfig.ts`
- `src/core/execution/SAMLauncherExecution.ts`

### What Changed
- `NukeExecution.detonate`: reduced call overhead/allocations by caching
`mg`/`config`, avoiding repeated lookups, and using allocation-free
loops (no `forEach` closures) in the diminishing-effect pass.
- `WarshipExecution.findTargetUnit`: replaced allocate+sort flow with
single-pass best-target selection.
- `UnitGrid.nearbyUnits`: reduced call overhead and allocations via
single-type fast path and cached query coordinates.
- `PlayerImpl.units`: added fast paths for common small-arity type
queries (1-3 unit types).
- `DefaultConfig.unitInfo`: cached `UnitInfo` objects per `UnitType` to
avoid repeated object/closure creation.
- `SAMLauncherExecution` targeting: removed sort churn and streamlined
target selection with single-pass hydrogen prioritization.



### Rebase
- One conflict was resolved in `NukeExecution.detonate` by keeping
`main`'s diminishing-effect-per-impacted-tile behavior, while retaining
the allocation-reduction refactors.

DevelopingTom 031a17d880 Optimize nuke explosion (#3176)
## Description:

When a nuke detonates, the explosion is looping over each tiles. Among
other things, it filters the owner units to find the `TransportShips`
units.

This operation is cpu-intensive and repeated over each tiles can make
the tick noticably slower.

On this screenshot the detonation function took 100ms:
<img width="1617" height="488" alt="image"
src="https://github.com/user-attachments/assets/07009b18-4342-4caf-9e82-9ae5147b63f8"

src="https://github.com/user-attachments/assets/fe9ead87-550a-4166-96ab-092d0c08be82"
/>

I suspect it led to a few frame freeze when I MIRVed too.

Suggestion: loop over the impacted players rather than the tiles.

With this suggestion, the same nuke takes between 4ms to 20ms:
<img width="989" height="365" alt="image"
src="https://github.com/user-attachments/assets/25c0faf0-cc34-41b7-8091-b14bde6db595"
/>


However this changes the death formula used, as they were repeated over
each tiles with ever-smaller values, and with this change the operation
is done all-at-once. This will result in a different outcome.

In my opinion the performance gain is seductive enough to maybe tweak
the formula to make it work with this revised strategy.
What do you think?

VariableVince 8b66c8bd53 Perf/refactor: use StructureTypes, remove territoryBound (#3238)
## Description:

PR 6/x in effort to break up PR
https://github.com/openfrontio/OpenFrontIO/pull/3220. Follows on already
merged https://github.com/openfrontio/OpenFrontIO/pull/3237.

Please see if these can be merged for v30.

- **PlayerImpl**: validStructureSpawnTiles did a filter on unit types to
get isTerroritoryBound units, on every call again. It read this from
unit info in DefaultConfig. While having it centrally in DefaultConfig
unitInfo is good for maintainability, other code uses hardcoded
StructureTypes and isisStructureType from Game.ts. Which has the same
purpose and thus contains the same unit types. StructureTypes and
isisStructureType do need manual maintainance outside of DefaultConfig.
And are more bug prone/less type safe. But, using them gives more speed
compared to getting these unit types out of DefaultConfig unitInfo
centrally with some cached function in GameImpl for example (tested with
buildableUnits and MIRVPerf.ts). So I went with StructureTypes in
validStructureSpawnTiles too.

- **PlayerExecution**: now validStructureSpawnTiles no longer needs
isTerritoryBound (see the point above), PlayerExecution is the last
place where it was used. Replaced it for isStructureType here too (since
it has the same meaning and outcome).

- **Game.ts** and **DefaultConfig** unitInfo: remove the now unused
_territoryBound_. As it was only used in validStructureSpawnTiles and
PlayerExecution and has been replaced in both (see the two points
above).

## Description:

PR 5/x in effort to break up PR
https://github.com/openfrontio/OpenFrontIO/pull/3220. Follows on already
merged https://github.com/openfrontio/OpenFrontIO/pull/3236.

Please see if these can be merged for v30.

**NationStructureBehavior**:
- maybeSpawnStructure: cache this.game to be used twice.
- maybeSpawnStructure: instead of hardcoded ruling out Defense Post for
upgrade check, check dynamically if type is upgradable. That way if
defense posts ever do become upgradable, we don't run into a bug right
away.

- maybeUpgradeStructure: removed canUpgradeUnit check. Since it already
checked this right before in findBestStructureToUpgrade, so only
upgradable units are returned. And canUpgradeUnit is also checked right
after in UpgradeStructureExecution. So we're going from 3 times to 2
times canUpgradeUnit, small perf win too.

- findBestStructureToUpgrade: cache this.game to be used thrice.

- shouldBuildStructure: cache this.game.config() to be used twice.

- getTotalStructureDensity: this.player.units can handle an array of
unit types to count. Input StructureTypes like this so we don't need a
loop and count, and only have to get an array length once.
getTotalStructureDensity needs to ignore unit levels so we can't make
use of other pre-defined functions in PlayerImpl (which were created to
avoid array length calls), but at least this saves a few.

Evan 2b830e9fcd Update tradeship spawn & gold meta (#3232)
## Description:

Now that pathfinding is much more efficient with hpa*, we can add more
trade ships.

This PR does the following:

1. No gold bonus for additional ports, keeps the meta simple
2. cut the gold per trade ship roughly in half.
3. Use a "pity bonus", the more times a port has failed to spawn a
tradeship, the higher the likelyhood it will spawn one
4. Increase the sigmoid so the mid-point is 200, with a half life of 50.
In tests about ~400 trade ships max.

It's pretty difficult to balance on singleplayer so I'm sure the values
will be adjusted after playtests.

Abdallah Bahrawi 7bf6bfd4b9 🔴 Major SAM Targeting Fix (#3223)
## Description:

Bug (before): In multi-nuke scenarios (e.g., 6 incoming nukes), SAMs,
when stacked, could behave like they only engage one nuke at a time,
letting other nukes slip through and wipe the SAM stack. This was most
noticeable when nukes entered from certain angles/entry sides (from what
I’ve noticed, it happens more often in the 2 o’clock to 6 o’clock
direction).

<img width="734" height="743" alt="asadasada"
src="https://github.com/user-attachments/assets/7ca6c9ef-b2b4-47ea-bed2-249a84c8f5ed"
/>

What was fixed:
1- Removed permanent "unreachable" caching: When a nuke was out of SAM
range on first evaluation, it was cached as null (permanently
unreachable) and never re-evaluated. Since nukes move each tick, they
could later enter interception range but would be ignored. The fix
removes this permanent cache, so nukes are re-evaluated every tick.

2 - Moved targetedBySAM filter into the targeting system: The
targetedBySAM() check was at the launch decision, if the
highest-priority nuke was already claimed by another SAM, the launcher
skipped firing entirely instead of falling back to the next best target.
The fix moves the filter inside getSingleTarget() so claimed nukes are
excluded before ranking.

3 - Cleared targetedBySAM flag on SAM missile abort: When a SAM missile
aborted (for example target became allied), the targetedBySAM flag was
never cleared. This permanently prevented all other SAMs from targeting
that nuke. The fix calls setTargetedBySAM(false) on abort so the nuke
becomes available for re-targeting.

**Videos:** 
I uploaded a before/after clip showing SAM performance intercepting 6
nukes, before the fix, nukes could break through, but after the fix,
SAMs consistently intercept as expected.

FloPinguin 86e51ab790 Fix nation spawnkilling 🔧 (#3222)
## Description:

As far as I can remember, in v28 the spawn immunity applied to both
humans and nations.
With the configurable spawn immunity (added for v29) the spawn immunity
no longer applies to nations... Because its called PVP immunity now.
So right now it's possible to spawnkill nations. This is a big problem
for the 5M gold modifier games... And you can "cheat" in singleplayer.

This PR changes two things:
- Nations always have 5 seconds spawn immunity now, no matter whats
configured for the PVP immunity
- Nations attack TerraNullius earlier (Otherwise the easy nations would
sometimes do their first attack after the 5 seconds are over, spawnkills
would still be possible)

- `NationMIRVBehavior`: Nations no longer MIRV enemies who already got
MIRVed in the last 30 seconds. Some humans complained about getting

nations MIRVed the same player (stop steamroll logic).
- `NationAllianceBehavior`: Fixes a comparison logic bug (Thanks to
Deshack)
- `NationNukeBehavior.ts`: Little atom bomb perceived cost balance
change
- `MIRVExecution`: To make sure the MIRVing nations are attacking the
MIRVed nations (even if they don't share a border), the relation gets

Mattia Migliorini f362e47413 Cancel nukes when accepting alliance via radial menu (#3155)
Resolves #3154

## Description:

#2716 introduced nuke cancellation logic on alliance acceptance via
`AllianceRequestReplyExecution`. The radial menu action, though, calls
`AllianceRequestExecution` instead, which accepts the alliance if a
request has already been made by the other player.

This PR moves the nuke cancellation logic to `GameImpl`, hooking into
the `acceptAllianceRequest` method, therefore accounting for every
alliance acceptance, regardless of the specific action that brought to
that.

DevelopingTom a1b3afe534 Fix cluster deletion (#3185)
## Description:

When a train station is removed, the clusters are recomputed. However
the cluster recomputation code has not been changed from the original
rail network implementation, which was a tree.

The deletion code made assumptions that are not true anymore since we
introduced loops in the network. As a result the cluster recomputation
was very inefficient, although the data was correct.

Changes:
- Fix clusters computation when a structure is deleted

- Structures are frequently deleted in bulk: atom/hydro/MIRV.
Re-computing the clusters when a single structure is deleted would be
inefficient because the recomputed cluster would probably need to be
recomputed again in the same tick.
Instead, when a structure is deleted, flag the cluster as "dirty", and
recompute all the dirty clusters once per tick only.

Previous performances (hydro over a dense area):

VariableVince 07e13b3479 Fix: remove alliances on death (#3168)
## Description:

- Remove alliances on death: after death, alliances would stay active
including countdown timers and (when dead player kept spectating) icons.
Now remove them when player becomes inActive.

- Moved code to private method within PlayerExecution + added comments
in NationExecution and BotExecution for more clarity as to where
removals are performed from at death

- Remove renewal request from Events Display when Alliance doesn't exist
anymore (after death or otherwise).

- Also cleanup this.alliancesCheckedAt when alliance doesn't exist
anymore. Before, old/broken alliance id's would accumulate in it during
a game.

- Removed now-redundant isAlive check in EventsDisplay. Both the
alliances array as the isAlive are updated in the same tick from
PlayerUpdates so now alliance is removed from alliances array on player
death, the other.isAlive() check is no longer needed. Of course we could
keep it in just to be very safe, so just let me know when you're
doubtful about this.

- Attack.test.ts: fix failing test. Player B dies because of the attack,
meaning the alliance now gets removed. Prevent this by gving both a
different, adjecent, starting tile. And to be more clear about what is
needed for the test to pass, add isAlive check for both of them after
the attacks.

FloPinguin f7da20ddfd Nation build order improvements + Nation structure upgrading 🏠 (#3152)
Resolves #2997

## Description:

### New stuff

- Nations can upgrade structures now. They do it if they have too many
structures compared to their territory size
- They prefer to upgrade stuff thats protected by SAMs (based on
difficulty)
- Updated the build order, it also depends a bit on the difficulty now
(easy nations build less SAMs)
- Nations can handle extreme amounts of gold now. 500M starting gold? no
problem. Previously they only built cities
- They stop saving up for MIRV if they can afford it (in some old Enzo
"impossible difficulty experiment" videos you could see nations with
like 300M gold...)
- The save-up-target changes when bombs / hydros / MIRVs are disabled
- Added many checks for disabled units. For example: Don't build SAMs
when missile silos are disabled, focus on factories when ports are
disabled
- Updated the `structureSpawnTileValue` method, SAM-placement depends a
bit on the difficulty now

### Refactor

- Moved all structure related nation code into
`NationStructureBehavior.ts`
- Split up the good old `structureSpawnTileValue` method to make it more
readable
- Cleaned up NationExecution a bit

DevelopingTom c6c793f6b3 Highlight hovering railroad (#3156)
## Description:


![rail_snap](https://github.com/user-attachments/assets/1dc66dc8-5df8-4826-8a8e-521d72a1f8aa)

The `RailroadLayer` simply displays tiles as instructed by the core
worker. While it's practical for the layer to only care about the tiles,
it also means it has no understanding of railroads as entities (their
paths, connections, or identities).

It also means that the core worker is responsible for rendering tasks
such as tile orientation and construction animation, which is not
expected.

To support ID-based events and better separation of concerns, the
rendering layer needs to be aware of complete railroads. With this
change, the core worker can send the tiles once and subsequently
reference railroads only by ID for all other events.

#### Changes:
- `RailroadLayer` now stores full railroad data instead of only
individual tiles
- `RailroadLayer` is responsible for animating newly built railroads
- Add a new `RailroadSnapUpdate` sent when a new structure is built over
an existing railroad. This event is used by `RailroadLayer` to keep
railroad ID in sync.

- When hovering over a railroad, the render worker is querying the core
worker about overlapping railroads.
Alternatively, RailroadLayer could compute overlaps itself now that it
has full railroad knowledge, but this logic would need to be duplicated
and kept in sync across workers. Keeping a single source of truth in the
core worker is preferred.


#### Edgecases:
- When a structure snaps over a railroad, the original railroad is split
into two new railroads. If the construction animation is still in
progress, instead of resuming the animation at the correct point on the
new railroads, all remaining tiles are rendered immediately
- Previously, `RailroadUpdate` handled both construction and
destruction. This no longer works with `RailroadSnapUpdate`, as event
ordering is now pretty important and IDs may be lost before they are
consumed.
To address this, RailroadUpdate is split in two:
`RailroadConstructionUpdate` and `RailroadDestructionUpdate`.

Ryan 8dcc7cfb9a Fix client reconnection after page refresh (#3117)
## Description:

- Removed all code related to generating a client ID on the client. The

scamiv 8cc6c2c2aa Perf spawn train (#3130)
## Description:

Train spawning hot-path optimization (trade destination selection)

## Summary
This PR reduces per-tick overhead in train spawning by removing
temporary allocations and reducing work in the
destination-selection path.

The change focuses on `Cluster` trade destination lookup and how
`TrainStationExecution` picks a destination.

## What changed
### 1) Maintain a “trade-capable” station subset per cluster
`src/core/game/TrainStation.ts`

- `Cluster` now maintains:
  - `stations`: all stations in the cluster (unchanged)
- `tradeStations`: maintained subset of stations that can act as trade
endpoints (`City` or `Port`)
- `tradeStations` is kept in sync in:
  - `addStation()`
  - `removeStation()`
  - `clear()`

Impact:
- Trade queries no longer scan every station in the cluster; they only
scan `tradeStations`.

### 2) Add cheap eligibility helpers
`src/core/game/TrainStation.ts`

- `hasAnyTradeDestination(player)`:
- Fast early-exit check: returns as soon as it finds any eligible trade
destination.
- `randomTradeDestination(player, random)`:
- Picks a random eligible trade destination directly without
materializing an intermediate `Set`.

### 3) Use reservoir sampling for single-pass random choice
`src/core/game/TrainStation.ts`

`Cluster.randomTradeDestination()` uses reservoir sampling:
- Iterates `tradeStations` once.
- Maintains a running count of eligible stations (`eligibleSeen`).
- Replaces the selected station with probability `1/eligibleSeen`.

Properties:
- Uniform selection among eligible stations.
- One pass instead of “count then pick by index” (two pass).
- Allocation-free.
- Returns `null` when no eligible destination exists.

### 4) Update train spawning to avoid temporary sets
`src/core/execution/TrainStationExecution.ts`

- Previously: `spawnTrain()` called `cluster.availableForTrade()` and
then `random.randFromSet(...)`.
  - This built a new `Set` on the hot path.
- Now:
  - Early-exit via `cluster.hasAnyTradeDestination(owner)`.
  - Destination via `cluster.randomTradeDestination(owner, random)`.

Net effect:
- Less per-tick work and no per-spawn temporary `Set` allocations.

## Why this helps
Train spawning happens frequently and can become a hot path in large
games / large rail clusters.
Avoiding repeated allocations and reducing work inside `tick()` helps
keep frame/update time predictable.

## notes
- Trade rules are unchanged (`tradeAvailable(player)` still gates
eligibility).
- Destination selection remains random-uniform over eligible
`City`/`Port` stations that satisfy `tradeAvailable(player)`.
- `TrainStationExecution` now avoids calling `spawnTrain()` entirely
when `spawnTrains` is falsy (it was already guarded inside).

scamiv b68de96c6e Perf clusters (#3127)
## Description:

This PR reduces server/client tick CPU spent on territory cluster
maintenance by:
- Cutting redundant work in `PlayerExecution.removeClusters()`
(largest-cluster bounding box reuse, fewer allocations in
`isSurrounded()` and `removeCluster()`).
- Making `calculateBoundingBox()` allocation-free per tile by switching
from `gm.cell(tile)` to `gm.x(tile)`/`gm.y(tile)` (it now only allocates
the two result `Cell`s, instead of 1 per tile).

## Commits
- `51de0a1b` core: reduce PlayerExecution cluster overhead
- `6d9d85c5` core: avoid Cell allocations in PlayerExecution
isSurrounded
- `346f6a8c` core(util): speed up calculateBoundingBox by avoiding Cell
allocations


## Notes
- This PR is intended to be behavior-preserving; changes are limited to
hot-path micro-optimizations.
- Follow-up opportunity: `calculateClusters`/flood-fill is now the top
hotspot; further wins likely come from reducing traversal work or
caching.

FloPinguin a8836f76d3 Reduce bot farming problem (#2895)
## Description:

Explanation of the bot farming strategy in the discord:
https://discord.com/channels/1359946986937258015/1359949371956789289/1460928540575928478
"the result is that a player can build unlimited factories for 125 000
gold discount, trade with themselves with each train being worth 50 000
gold. First the 25 000 for neutral trade and then another 25 000 when
the bot is harvested."
"If you have a minute and ally people around you it should be trivial to
get 10 of both cities and factories for 1.25mil"

It's debatable if we want to let people do that (close this PR) or see
it as an abusive mechanic.

Here is the fix, bots try to delete all structures now. You can simply
retake them to stop the deletion:

FloPinguin f7d3c2e0bc Nations donate troops now 💀 (In team games) (#2984)
## Description:

For v29, balances the HvN winrate.

In team games, nations now donate troops to their weakest team members
(if they have no attack options available).
How often they donate depends on the difficulty.

This PR also has some other little fixes:
- For HvN games, always return true in `shouldAttack()` (make nations a
bit more aggressive).
- Early exit in `attackWithRandomBoat()` for performance
- Early exit in `findNearestIslandEnemy()` for performance AND to make
sure nations which are encircled by friends don't run into this method
(=> no donation happening!)
